Hybrid multiple access apparatus and method in a mobile communication system

摘要

A hybrid multiple access apparatus and method in a mobile communication system supporting various multiple access schemes are provided, in which an initial service negotiation is performed in a non-orthogonal transmission scheme between an MS and a BS, the BS receives from the MS an orthogonal resource request for high-speed packet data transmission, and the BS allocates orthogonal resources to the MS based on channel estimation information indicating a channel status between the MS and the BS.
